The invention relates to guiding instruments for guiding an acetabular cup implant as well as to impactors for press-fitting an acetabular cup implant, both of which are of use during reconstructive joint surgery, more specifically during reconstructive hip joint surgery. At least one coupling assembly is engageable about an end of the linking member extending from the spinous process. The conveyor can be a wire conveyor having wires having a thickness so that they can support the food items, which can be eight to ten pounds, while being small enough so that the they do not block ACS solution sprays from the bottom nozzles, or do so to a negligible degree.
